Load the reference spectra for plotting, if set with
refSpecList.
# refSpecList is specified in YAML params. Can be one or multiple species

}Event summaries
Loop through each detection event (n = 92) create plots and a table of summary statistics for click and whistle detections. This process uses AcousticStudy objects that have detection data for each event, and also pulls information from the Pamguard binaries associated with each AcousticStudy.
Click plots (other than the SNR plot) only show clicks with SNRs >= 15 dB.
